Problems solved by technology

Although the purpose of energy saving and pollution reduction can be achieved after adding diesel emulsifier, there are still technical difficulties in oil-water stability and corrosion; there are gray-type additives containing metal elements. Due to the addition of metal elements, many places in the cylinder and nozzle are caused Dust accumulation will affect the performance of the engine, and its combustion products will cause secondary pollution (including the emission of metal particles and toxic metal compounds), making its application doubtful

Embodiment 1

[0016] The ashless additive for diesel engines of the present invention is prepared in the following proportions in terms of mass percentage: 60.3% of ethyl lactate and 39.7% of tert-butyl peroxy-2-ethylhexyl carbonate. Taking 10.00 g of the total weight of the ashless additive as an example, weigh 6.03 g of ethyl lactate and 3.97 g of tert-butyl peroxy-2-ethylhexyl carbonate.

[0017] Put 6.03g of ethyl lactate and 3.97g of tert-butyl peroxy-2-ethylhexyl carbonate into a container, and mix them uniformly with an ultrasonic stirrer at normal temperature and pressure to prepare a transparent ashless diesel additive solution. The amount added in diesel is 2 / 623 of that of diesel, that is, added to 3115g of diesel and stirred evenly.

[0018] The engine bench test was carried out according to GB / T18297-2001 (automobile engine performance test method), the fuel consumption decreased by 2.29%, the CO emission decreased by 33.6%, the HC emission decreased by 86.3%, and the NO x Emi...

Embodiment 2

[0020] In terms of mass percentage, it is prepared according to the following proportions: 51% ethyl lactate, 49% tert-butyl peroxy-2-ethylhexyl carbonate. Taking 10.00 g of the total weight of the ashless additive as an example, weigh 5.1 g of ethyl lactate and 4.9 g of tert-butyl peroxy-2-ethylhexyl carbonate.

[0021] Put 5.1g of ethyl lactate and 4.9g of tert-butyl peroxy-2-ethylhexyl carbonate into a container, and mix them uniformly with an ultrasonic stirrer at normal temperature and pressure to prepare a transparent ashless diesel oil additive solution. The amount added in diesel is 1 / 398 of diesel, that is, added to 3980g of diesel and stirred evenly.

[0022] Carry out the engine bench test according to GB / T18297-2001 (automobile engine performance test method), fuel consumption decreased by 1.67%, CO emission decreased by 25.8%, HC emission decreased by 80.2%, NO x Emissions decreased by 5.37%, and smoke decreased by 16.9%.

Embodiment 3

[0024] In terms of mass percentage, it is prepared according to the following proportions: 80% ethyl lactate, 20% tert-butyl peroxy-2-ethylhexyl carbonate. Taking 10.00 g of the total weight of the ashless additive as an example, weigh 8 g of ethyl lactate and 2 g of tert-butyl peroxy-2-ethylhexyl carbonate.

[0025] Put 8g of ethyl lactate and 2g of tert-butyl peroxy-2-ethylhexyl carbonate into a container, and mix them evenly with an ultrasonic stirrer at normal temperature and pressure to prepare a transparent ashless diesel additive solution. The amount added in diesel is 1 / 296 of diesel, that is, added to 2960g of diesel and stirred evenly.

[0026] According to GB / T18297-2001 (automobile engine performance test method), the engine bench test was carried out, the fuel consumption decreased by 1.83%, the CO emission decreased by 22.4%, the HC emission decreased by 82.9%, and the NO x Emissions decreased by 7.51%, and smoke decreased by 17.7%.

Abstract

The invention relates to an ashless additive for a diesel engine and the application of the ashless additive, and belongs to the technical field of diesel additives. The ashless additive for the diesel engine comprises the following components in percentage by mass: 50 to 83 percent of ethyl lactate and 17 to 50 percent of tert-butyl peroxy-2-ethylhexyl carbonate. The ashless additive can be used for improving the combustion performance of diesel and fulfilling the aims of saving the diesel and reducing the emission of harmful substances after combustion used as an anhydrous metal-free diesel additive.

Description

technical field [0001] The invention relates to an ashless additive for diesel engines and its application, belonging to the technical field of diesel additives. Background technique [0002] Energy is one of the important material foundations for the survival and development of human beings. The urgent problem facing the world today is the shortage of fossil energy. The important aspects of the green strategy are to improve energy utilization efficiency and environmental protection. [0003] Compared with gasoline engines, diesel engines have high combustion efficiency, good durability, and low maintenance requirements. Therefore, diesel vehicles have many advantages in saving energy, reducing energy security risks, and reducing greenhouse gas emissions. However, the problems of diesel as a power fuel cannot be ignored. Small view, particulate pollutants (PM) and NO from diesel engines x Because of the large amount of discharge and complex control technology, it has become...
